This parameter allows the operation of the buzzer to be configured. It can be set for activation by time (automatic silencing) or
alternatively kept on until the alarm condition no longer exists or the operator intervenes. The times available are: 1, 2, 5, 10, 15
and 20 minutes.
$ODUPUHOD\DFWLYDWLRQWLPH
This parameter can be used to modify the type of activation of the local alarm relay. Fixed activation can be set, or alternatively
activation by time. The times available are 1, 2, 5, 10, 15 and 20 seconds.

Activating this parameter allows the status of the local relay to be repeated by the relay on the printer board. In this case, the
relay can only be set for fixed activation, that is, activated in the presence of an alarm and deactivated when there are no alarms.
The logic, that is, de-energised or energised during an alarm depends on setting of the corresponding dip-switch on the board.
With this option enabled, the printer board relay continues to perform the function of watch-dog for the RS485 network,
becoming the logical OR for the network alarm condition (WatchDog) and alarms generated by PlantWatch..
$ODUPUHOD\ORJLF
Allows the setting of two configurations, normally energised or normally de-energised, for the local alarm relay.

The second relay, (
(

alarms corresponding to the internal operation of

These parameters allow sampling frequency of the variables to be set. For further details see the corresponding chapter.

Enabling this parameter allows local and remote signals to be activated for the automatic download of the logs to the service
centre and to warn the user of the risk of data loss in the case of failed download via serial line or printer.

The generation of the memory full alarms depends on the percentage of the free space available for saving the data. The resetting
of this indicator must be selected depending on the mode used to the save the log, that is, printing the report or sending the log to
a service centre, so as to ensure that failed connection to the service centre or incomplete printing of a report will activate the
alarm.
